Jason,
The auto-x this Sunday should have the most entrants, but since the April 28 event is the first open Corvette club event, who knows how many they will have.
Yes get there early. This will give you more run choices as well as more time to get everything done before the heats start. If you make it out Sunday, look me up. I will be in a white Miata
w/ SSR Competition wheels and the roll bar. If that doesn't help, look for Tony's black CSVT or Jerry's silver CSVT (Jerry and Tony, sorry I voluteered you

) . One of us should be able to get you going in the right direction. If you come, plan on running because this is a participation sport and there are loaner helmets. Hope to see you there on Sunday ready to run. When you run on Sunday, I'll give you any help I can.
Respectfully,
Andy Hohl
